In Venture Into the Beyond, a veteran crew answers a rich priest’s call to descend into the vast pit beneath Lincoln in search of the legendary Black Diamond, a mythical ore said to lie somewhere in Lumen’s deepest dark. What starts as a paid expedition quickly turns into something stranger as old world ruins, undeciphered texts, local warnings, and a mirror that should not exist all point to powers far older than the town above. And when the party finally pushes deeper into the pit’s deadly lower reaches, the climb turns brutal fast as wyverns descend and the abyss reminds them exactly why so few ever return.
